Activation system for actuators of a vehicle seat device

Abstract

An activation system for actuators of a vehicle seat device, including a first control device; a gas pressure accumulator having a gas pressure accumulator valve situated on it; a pressure distribution device functionally connected to the gas pressure accumulator; and a connecting device situated between the first control device and the pressure distribution device, the actuators being activatable as a function of an accident characteristic which is ascertainable with the aid of the first control device and which is transmittable to the pressure distribution device.

What is claimed is: 
     
       1. An activation system for actuators of a vehicle seat device, comprising:
 a first control device configured to control the actuators; 
 a gas pressure accumulator having a gas pressure accumulator valve situated on the gas pressure accumulator; 
 a pressure distribution device functionally connected to the gas pressure accumulator; and 
 a connecting device situated between the first control device and the pressure distribution device, the actuators being activatable as a function of an accident characteristic which is ascertained by the first control device and which is transmitted to the pressure distribution device; 
 wherein the pressure distribution device includes at least two gas outlet valves and a second control device configured to control the at least two gas outlet valves according to the accident characteristic. 
 
     
     
       2. The activation system of  claim 1 , wherein the connecting device includes an electronic data line. 
     
     
       3. The activation system of  claim 1 , wherein the gas pressure accumulator valve is controllable with the aid of the second control device. 
     
     
       4. The activation system of  claim 1 , wherein the gas pressure accumulator valve has a pressure sensor. 
     
     
       5. The activation system of  claim 1 , wherein the actuators are at least one of directly activatable and indirectly activatable with the aid of gas pressure of the gas pressure accumulator. 
     
     
       6. The activation system of  claim 1 , wherein the at least two gas outlet valves are variably controllable as a function of time with the aid of the pressure distribution device. 
     
     
       7. The activation system of  claim 1 , wherein the gas pressure accumulator is directly connectable to the pressure distribution device. 
     
     
       8. The activation system of  claim 1 , wherein the gas pressure accumulator includes a cold-gas pressure accumulator. 
     
     
       9. The activation system of  claim 1 , wherein a portion of a frame of the vehicle seat device is designed as a sole or at least an additional gas pressure accumulator. 
     
     
       10. The activation system of  claim 1 , wherein the system is at least partially situated in a seat pan of the vehicle seat device. 
     
     
       11. The activation system of  claim 1 , wherein the system is at least partially situated in a backrest of the vehicle seat device. 
     
     
       12. A method for activating actuators of a vehicle seat device, comprising:
 ascertaining an accident characteristic by a first control device configured to control the actuators; 
 transmitting the accident characteristic from the first control device to a pressure distribution device having at least two gas outlet valves and a second control device, wherein the actuators are activatable as a function of the accident characteristic ascertained by the first control device and transmitted to the pressure distribution device; 
 controlling the at least two gas outlet valves of the pressure distribution device by the second control device as a function of the accident characteristic; and 
 controlling, by the second control device, opening of a gas pressure accumulator valve of a gas pressure accumulator connected functionally to the pressure distribution device. 
 
     
     
       13. The method of  claim 12 , wherein the gas pressure accumulator valve is controlled in a time-variable manner. 
     
     
       14. The method of  claim 12 , wherein the at least two gas outlet valves of the pressure distribution device are controlled in a time-variable manner.
